Okay, I understand why are you doing it. Even if I don't give you the information you need, it's available here on SNB Forums. So here it is:
Routers with good VPN capabilities (~200Mbps) have ARMv8 + AES CPU. The cheapest one with expected longer support is RT-AX68U, but it has some 5GHz connection issues reported and is not very popular choice here. The next model up is RT-AX86S with better reliability and Wi-Fi capabilities. Both are Asuswrt-Merlin supported models. If you don't really care about future firmware updates, older RT-AC86U also has the CPU you need. This router though has a history of hardware and software issues. If you find one much cheaper than the two above, get the maximum warranty possible. Don't buy RT-AC86U second hand - new only. It runs well with current Asuswrt-Merlin 386.7_2 firmware.
Be careful with the model numbers. They are similar and confusing sometimes. Good luck!
